Re: [PATCH 1/9] Fix git patch header processing in git-apply.

Thanks for "apply" patches. I have merged some of them and pushed out.

I further wanted to apply the following to the proposed updates branch, but even with only the first one applied, it fails its own test, t4104-apply-complex.sh:

* Fix processing of a patch file which modifies the same file in git-apply.
* Fix the processing of multiple patch files with --check in git-apply.
* New option --ignore-whitespace for git-apply.
* New option --ignore-applied for git-apply.
